WILLIAM H. HUNT, OF NEW YORK, N. Y.

HATCH-COVER LIFT.

Specification of Letters Patent.

Patented Sept. 25, 1917.

Application filed April 28, 1917. Serial No. 165,103.

To all whom it may concern:

.Be it known that I, VILLIAM H. HUNT, acitizen of the United States, anda resi dent of the city of New York, borough of Manhattan, in the countyand State of New York, have invented a new and Improved Hatch-CoverLift, of which the following is a full, clear, and exact description.

This invention relates to lifting devices for lids or, rather, coveringmembers, and has for an object the provision of an improved constructionfor raising the covers of the hatches of ships in such a manner as toquickly and easily remove any cover or all covers simultaneously.

Another object in view is to provide an improved arrangement of liftingdevices for hatch covers which will allow the easy raising of hatchcovers of any weight quickly and by a minimum manual effort.

In the accompanying drawings Figure 1 is a top plan view of part of thedeck. of a ship showing the hatch covers in place and an embodiment ofthe invention associated therewith.

Fig. 2 is a fragmentary transverse sectional view on an enlarged scalethrough Fig. 1 on line 22.

Fig. 3 is a fragmentary sectional view,

through Fig. 2 on line Fig. 4 is a transverse horizontal sectional viewthrough Fig. 3 on line Fig. 5 is a detail enlarged fragmentary sectionalview through Fig. l on line 55.

Fig. (3 is an enlarged detail fragmentary sectional view through Fig. 1on line (16.

Referring to the accompanying drawings by numerals, 1 indicates the deckof a vessel of any kind, provided with hatches 2 of any desired kind orusual. construction, said hatches being provided with covers 3, 4, 5 and(i, said covers being held in place by a At the point where the covers 3and 4 come together and also where the covers 5 and (3 come together arearranged straps 8 and 9 overlapping the joint so as to make a watertightconstruction. The detail construction of the covers 3 to 6, inclusive,may be of any kind withcut departing from the spirit of the inventionprovided they are hinged in position as shown in Fig. 1 and alsosupplied with eyelet members 10 to which the various cables 11, 12, 13and 14- are respectively connected. The cables 13 and 14 pass overpulleys 15 and 16 and from thence downwardly over pulleys or sheaves 17and 18 (Fig. 2) and from said sheaves extend to pulleys or sheaves 19and 20 near the end of the hatches. The ends of the cables 13 and 11 areprovided with hooks, rings or other connecting means whereby the cable21 may be connected therewith in order that when the cable 21 is woundup or pulled by the winch on the ship the covers 4 and will be raised oropened. It is evident that the cable 21 could be connected to either ofthe cables 13 or 14 so as to raise either cover independently.

The pulleys 15 and. 16 are rotatably mounted upon a shaft 22 journalcdin the upstanding walls 23 and 24 of the standard 25, said walls merginginto a top covering member 26; The standard 25 is preferably cast so asto make the construction shown in Fig. 3, which includes a bottombracing member 27, said bracing member and the sides 23 and 24 merginginto a central web 28 and into side webs or flanges 29 and 30 as shownin Figs. 3 and 4. The entire construction tapers as shown in Fig. 2 sothat the parts are properly braced, the lower end being provided with asolid piece Sl'which may be bolted or in any suitable way connected withthe deck 1 of a ship. The standard 25 and also the standard 32, whichidentical with standard 25, are permanently fixed and will remain inposition at all times so that the covers may be raised whenever desired.

Suitable locking bolts 33 (Fig. 5) are provided which extend throughnotches 34 in retaining straps 35, said bolts being pivotally connectedwith the various hatches 2. After the bolts have been loosened and movedto one side the covers may be raised mai'iually by one or more personslifting upwardly thereon or may be raised by operating the respectivecables connected thereto. It will be observed that the construction ofthe standart 33 and arrangement of pullcys, cables and which cable areidentical with the structure shown in connection with standard 25 sothat no additional description will be necessary. By connecting both ofthe winch cables to the lifting cables all of the covers may be raisedsimultaneously or by connecting any one or more of the lifting cables tothe winch cables the desired number of covers may be lifted.

What I claim is: 1. A lifting device for hatch covers, comprisinglifting cables, pulleys for guiding said lifting cables, and a standardfor carrying some of said pulleys, said standard comprising an uprightmember having a boxing or casing at the upper end for receiving thejournal member of some of said pulleys, and a base capable of'receivingsecuring means for securing the standard to a ship.

2 A hatch cover lift, comprising a cable for each cover, means forconnecting said cables to said covers, a plurality of pulleys forguiding said cables, and a standard for supporting some of said pulleys,said standard being formed With a central Web and a pair of side websfor bracing the central web, said side Webs merging into a casing at theupper end open on two sides for carrying the journal of the pulleyssupported by the standard and for protecting said last 20 mentionedpulleys.
